They are 'on average' equally spaced.  The code that shoots photons actually
jitters phi and theta to remove artifacts but that still maintains the
overall density.  And the overall density is all that I am worried about
for photons.  When you're creating a sphere of spheres, the geodesic
patterns will give you more uniform results.
